Filming for The Walking Dead season eight is now well underway as Rick Grimes (played Andrew Lincoln) and his pack take down Negan (Jeffrey Dean Morgan).

And it seems fans won’t even be given a chance to breathe as Steven Ogg – who plays Savior, Simon – promised the highly-anticipated premiere, which also marks the zombie epic’s 100th episode, will be one of the most explosive instalments to date.

“I mean, I really didn't think about the 100 thing so much as it's, where it says it's all-out war, you definitely get that,” he told ComicBook.com.

"Oh yeah. It's all-out war," he added. "[It's] a big, big show."
